Why add a sauna to your weekly routine?
Here are some of the strongest reasons, tied to research, for why a weekly sauna session is worth including.
1. Cardiovascular & longevity benefits
Regular sauna bathing is associated with lower risk of cardiovascular death, reduced blood pressure and improved vascular health. For example:
In a large Finnish cohort, people using a sauna 4-7 times per week had substantially lower risk of fatal cardiovascular disease compared to those using one once a week
Experimental studies show that just 30 minutes in a sauna led to a drop in systolic blood pressure and improved vascular compliance (i.e., the ability of arteries to expand) likely contributing to the long-term benefit.Â
A review article describes sauna use as a âprobable means to extend healthspan,â via repeated mild heat exposure triggering protective mechanisms.Â
So, incorporating even a single sauna session weekly may help support your cardiovascular system and overall longevity.
2. Improved blood flow, lower blood pressure, exercise-like effect
Being in a sauna raises heart rate (sometimes to the range you get during moderate exercise) and causes vasodilation (widening of blood vessels).
One study saw heart rate jump and vascular stiffness drop after sauna exposure.Â
The heat load acts similarly to low-moderate intensity exercise on the circulatory system. BioMed Central+1
So a weekly sauna is like giving your circulatory system a âgentle workoutâ + rest at the same time.
3. Stress relief, mental-health boost & better recovery
Saunas help activate the parasympathetic (ârest & digestâ) nervous system, reduce stress hormones, and promote relaxation:
A comprehensive review found sauna bathing is associated with better quality of life, improved mental health, and relief of symptoms like headaches and arthritis.Â
The relaxation and heat-exposure may also support sleep quality by helping regulate body temperature and calming the nervous system. UCLA Health
4. Nature-rooted sauna: amplifying benefits
If that sauna is in or around nature (trees, fresh air, wood surrounds), you gain extra benefit from being in a natural environment.
